QuestionHello:Two years ago I transplanted two rhubarb plants and, even now, they don't seem to be making much progress. THey are located in a sunny area,I fertilized them but the stalks are still pencil thin. What can I do????? Any advice would be most welcome./
AnswerBob:
I've never grown rhubarb, so I can't speak from experience. However, it is a perennial, and a slow growing one, so first I would say maybe it just needs another year. It's possible you damaged the plant somewhat when transplanting, divided at the wrong time or the plants were too young to be divided (were they at least 3 years old and crowded?) I assume they were producing well at the time of transplanting?
You already fertilized, you don't say when, twice a year would be OK. If the plants look healthy otherwise, I'd say again to just give them more time. You might do a soil test and make sure the soil where you transplanted them is the correct pH for rhubarb - I believe it likes acidic soil.
Sorry I can't be of more help.
